IJM012 Surface Quality of Metallic Microstructures Produced by Pulsed Laser-Based Manufacturing

Abstract

In this work, material removal process was performed using pulsed Nd:YAG laser of 60kW peak power to manufacture microstructures from Inconel samples at micrometer dimensions for micro-stamping and micro-embossing on metals. Effects of laser power density, overlap between laser pulses and processing velocity on the quality of the machined surfaces were determined. The surface roughness was decreased to about 1 micron as the velocity of laser beam was increased to 300 mm/s.
